The number of stereoisomers has to be identified when the reaction of 2-pentanone with ethyl magnesium bromide followed by the addition of dilute acid. Concept introduction: The Grignard reaction: Alkyl, vinyl, or aryl-magnesium halides ( RMgX ) is called as Grignard reagent. Grignard reagent is reaction with carbonyl compound such as aldehyde or ketone , produces corresponding alcohol is the product and it is the one of the carbon – carbon bond forming reaction. Stereoisomers: Stereoisomers are molecules that have the same molecular formula and they differ only in arrangement of atom in three-dimensional space.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

For each reaction below, decide if the first stable organic product that forms in solution will create a new CC bond, and check the appropriate box. Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. ?
